Hermes Agent is a desktop AI agent built by Nous Research that runs natively on macOS, Windows, and Linux. It's designed for people who want a single agent that works across their communication tools, handles recurring tasks, and actually remembers what it's done before.

The core idea is persistence. Most agents start fresh every session. Hermes maintains memory across conversations, auto-generates skills from past interactions, and builds up context about your projects over time. You don't have to re-explain things.

Where it connects:

• Telegram, Discord, Slack, WhatsApp, Signal, and email are all supported natively, so the agent meets you where you already work
• A CLI interface is also available for terminal-first workflows

What it can do:

• Natural-language scheduling for reports, backups, and briefings that run unattended
• Web search and browser automation with vision, image generation, and text-to-speech
• Subagents that run in isolated conversations with their own terminals and Python RPC scripts, useful for parallel pipelines without ballooning context costs
• Multi-model reasoning with access to 300+ models through the Nous Portal

Sandboxing is a genuine differentiator. Five execution backends (local, Docker, SSH, Singularity, and Modal) give you control over where code actually runs, with container hardening and namespace isolation. That matters if you're running automated tasks or untrusted scripts.

For teams or individuals already using LobeChat or similar multi-surface chat interfaces, Hermes takes a different angle: it's less about chat UI and more about an agent that operates autonomously across surfaces. Think of it as closer to an AgentOS approach, where the agent itself is the persistent layer.

It's free to use under the MIT license, with paid tiers through the Nous Portal for higher model access and monthly credits.
